LG Refrigerator Water Dispensing Switch Testing and Replacement

Introduzione

Use this guide to test and replace the water dispensing switch on your LG refrigerator.

This guide will work for most LG refrigerators. This guide is written with an LG model LFX25973 refrigerator. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.

The water dispensing switch triggers a solenoid valve in the refrigerator so that it dispenses chilled water through the dispenser.

If the switch fails, the refrigerator will either not dispense water or won't stop dispensing water.

The repair is moderately difficult. The removal of the dispensing unit is probably the most challenging step.

    • The dispenser assembly is secured by very strong clips, making it very difficult to remove. Take note of the clip location examples shown in the photos:

    • Right side clips

    • Top clips

    • Left side clips (Note, the dispenser is being held upside down for the photo, so the upper left side clips are at the bottom of the photo.)

    • During disassembly, you may break some of these clips. If you do, don't worry; the assembly does not need all the clips to be properly secured.
